Hi! 

I'm going through the Trailhead quizzes, and I've come to the ones that say "Connect to your Developer Edition" in order to complete the quiz.  I have a Developer Edition account set up, but when I try to access it through Trailhead it gives me this message: "Houston, we have a problem... you are attempting to log into Trailhead to complete challenges with an org that isn't supported.  When you are completing Trailhead hands-on challenges, you cannot use a production or sandbox org...." Anways, I'm not sure how to complete the quizzes. (They are under Learn CRM Essentials)  Any insight is greatly appreciated! 




 

I'm doing the simple lightning components challenge and have hit this problem in my existing trailhead org and a brand new dev org that I've just created:

Challenge not yet complete... here's what's wrong: 
There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: QVWBQHAG
